Hi All,
Back to this again after a while, got all working fine started working on other odd jobs before finally putting the roof on this week.
Got back to the pump and its making a "farty" noise , sounds like its trying to grind itself to death!
Think its time to source a nice quiet pump

Sometimes the solenoid valves don't flip when they are supposed to (the changeover relay sometimes doesn't latch), which can lead to the valves locking closed in both directions and the pump straining against the pressure relief valve. Is that the rude noise you are describing?

The Smiths mini-pack is a very noisy, but highly reliable hydraulic pump. Try flipping the relay a few times to see if the problem clears.

Only suggesting it because mine did the same thing last week, but in my case being laid up for several years clearly didn't help!

Thanks Lauren,
Yep got it bang on! I noticed the pump only travelling in the downward direction. It was the brand new VW relay I bought that was the problem. Opened up the relay and the very thin metal strip was not properly alternating left and right.
All good now . Even got the remote canopy working as well.

No, looks like pump is OK which will save spending further money. I don't mind it been noisy , more concerned over the reliability of the relays , so I'll keep the old skool one on hand in the car from now on.
